TYPOG-RAPHICAL COMPOSING-MACHIN E.

Specification of Letters Patent.

Application filed April 22, 1912.

To all u1/tom z' may concern Be it known that I, JOHN R. ROGERS, a l

citizen of the United States, and a resident of Brooklyn, State of NewYork, have invented a new and useful Improvement in TypographicalComposing-Machines, of which the following is a specification.

My invention rela-tes to typographical composing machines, such as linecasting machines of the general organization represented in my formerLetters Patent of the United States, No. 955,695 andY No. (379,481,wherein circulating matrices are released from their place of storage inthe order in which their characters are to appear in print andtransferred to the face of a mold, the mold lled with molten metal toform a slug or linotype against the matrices which produce the typecharacters thereon, and the matrices thereafter returned to the place ofstorage from which they st-arted. In the said patents, the matrices areof the captive or suspended variety, that is to say, they are mountedupon guides or wires,

along' which they pass to the place of assemblage.

It sometimes happens, and particularly7 in connection with matrices ofthe kind referred to, that when released by the escapement, they aresluggish or slow to move, which tendency is accentuated in the eventthat the parts are rusted or are not perfectly clean, and this hesitancymay result either in the transposition of characters in the composedlinea-or even in the complete arrest of the matrix before it reaches theline. l

It is the purpose of my invention to overcome these and similardisadvantages, and to this end I provide means which automatically actupon the released matrix to overcome its inertia and to accelerate it inthe direction of its normal travel. Preferably these accelerating meansare connected to the escapement, and in the specific form shown anddescribed, they comprise a rotary disk operatively connected to aspring, the various positions of which are automatically controlled bythe actuation of the escapement.

In the accompanying drawing, I have shown my improvement by way ofexample and in preferred form, and as applied to the coiuity of Kings,andk specific kind of machine already mentioned,

but obviously many changes and variations may be made therein, andsimilarly it may be used in connection with other typographicalcomposing machines, such as typesetters, typecasters, and the like, andin connection with free type or matrices, without dev parture from itsspirit; and generally speaking, I desire it to be understood that I donot limit myself to any specific form or embodiment except in so far assuch limitations are specified in the claims.

Referring to the drawing: Figure l is a perspective view of theescapement, with my invention applied thereto; Fig. 2 is a side view ofthe same, illustrating t-he parts in diiierent position; Fig. 3 is asimilar view, illustrating the parts in still another position; and Fig.I is a perspective detail, showing the other side of the acceleratingdisk.

Referring to the drawing, the general construction and arrangement is ormay be substantially the same as in my previously mentioned LettersPatent. The matrices A are normally suspended from and stored upon theguide or wire A1. Their individual release is governed by an escapementcomprising the pawls B and C connected to the rocking lever D. A springF connected to the pawl C'holds the parts in the position shown in F ig.l, and the escapement is operated from the keyboard by the connection E,in the customary manner. In the normal position of the parts, the pawl Bstands in front of the matrices and the pawl C is elevated. When theconnection E is o-perated, the lever D is swung about its pivot toelevate the pawl B and depress the pawl C, thereby releasing theforemost niatrix and interposing the pawl C before the remaining ones,as illustrated in Fig. 2.

It sometimes occurs, and due to a variety of reasons, that the releasedmatrix acts sluggishly and does not pass quickly along the guide or wireA1 to its destined position in the composed line. To overcome theinertia of the matrix and toaccelerate it in its normal path along theguide or wire, I employ additional means which are preferably connectedto and operated in unison with the escapement. In the specific formshown and described, these means comprise the rotary disk G, formed witha projecting y rices. IVhen the escapement is actuated vin f the Imannerpreviously mounted up on described, the disk Gr is reciprocated about`its axisA so that its lip G1 will engage and accelerate the releasedmatrix, and to this end I provide the depending arm K, which ispivotally the escapement lever I) and normally held by a spring K2 inits innermost or active position, that is to say, with its end over andin readiness to engage a pin L projecting from the side of the disk G(see Fig. 4). Thearm K is formed with the curved slot K1 to engage afixed stud J1 upon the frame plate J.

The operation of the parts will now be clearly understood. Ihen theescapement lever I) is 'swung about its pivot by the connection E, thesuspended arm K is moved downwardly, and by reason of its engagementwith the pin L, the disk Gr is rotated about its axis against the forceof the spring H, so as to bring the lip G1 above and in position toengage the matrix released by the pawl B (see Fig. 2). The downwardmovement of the arm K, and due to the engagement of the slot K1 thereinwith the fixed stud J1, has also shifted it laterally with relation tothe pin L on the disk G, and as the movement continues, the arm Kbecomes disengaged from the pin L (see Fig. 3), whereupon the spring Hacts suddenly to rotate the disk Gr in the reverse direction, and thelip G1 thereon engages the released matrix A and assists in overcomingits inert-ia and accelerates it in the direction of its normal travelalong the guide or wire A1. This action restores the disk G to itsnormal position, and upon the return movement of the escapement, the armK is again movedv inwardly by the spring K2 int-o operative relation tothe pin L. The parts are now in readiness to repeat their operation whenthe escapement is again actuated.

As previously stated, I have illustrated my invention by way of exampleand in preferred form, but obviously many modifications and variationsthereof will suggest themselves to those skilled in the art and still becomprised within its scope.

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States, is as follows:

1. In a typographical composing machine, the combination of a suspendedtype or matrix, its suspending guide, an escapement therefor, and adevice to overcome the inertia of the type or matrix and accelerate italong its guide.

2. In a typographical composing machine, the combination of a suspendedtype or matrix, its suspending guide, an escapement therefor, and adevice connected to the escapement to accelerate the type or matrixalong its guide.
